    • The invention relates to an optical recording medium comprising a substrate, a reflecting layer and a recording layer, which recording layer consists essentially of a dye of the formula (I), ##STR1## in which R.sub.1 and R.sub.6 are hydrogen or unsubstituted or substituted alkyl, alkenyl, alkynyl, aralkyl or aryl, R.sub.6 and R.sub.7 are unsubstituted or substituted alkyl, alkenyl, alkynyl, aralky or aryl, R.sub.3, R.sub.4, R.sub.8 and R.sub.9 are hydrogen, halogen, OR.sub.17, SR.sub.17, NR.sub.18 R.sub.19, NO.sub.2, alkyl, alkenyl or Alkynyl, R.sub.5 and R.sub.10 are hydrogen, halogen, OR.sub.17, SR.sub.17, NO.sub.2, NR.sub.18 R.sub.19 or unsubstituted or substituted alkyl, alkenyl, alkynyl or aralkyl, and R.sub.11 is hydrogen, (CH.sub.2).sub.1-10 COO.sup.-, (CH.sub.2).sub.1-10 COOR.sub.24, alkyl, alkenyl, alkynyl or unsubstituted or substituted aralkyl or aryl; Y is the anion of an inorganic, organic or organometallic acid, Z is a metal cation, ammonium cation or phosphonium cation, m, n and o are from 1 to 3, and p and q are from 0 to 4; and the stoichiometry of o, p and q is such as not to result in any excess positive or negative charge in the formula (I). The substituents can, if desired, be connected to one another in such a way, via a direct bond or via a bridge --O-- or --NR.sub.12 --, as to form additional five- or six-membered rings. The novel recording media are of high sensitivity and have good reproduction characteristics.
    • 本发明涉及一种光记录介质,其包括基板,反射层和记录层,该记录层基本上由式(I)的染料,其中R 1和R 6为氢或未取代的 或取代的烷基,烯基,炔基,芳烷基或芳基,R6和R7是未取代的或取代的烷基,烯基,炔基,芳基或芳基,R3,R4,R8和R9分别是氢,卤素,OR17,SR17,NR18R19, ,烯基或炔基,R 5和R 10是氢,卤素,OR 17,SR 17,NO 2,NR 18 R 19或未取代或取代的烷基,烯基,炔基或芳烷基,R 11是氢,(CH 2)1-10 COO-,(CH 2) 烷基,烯基,炔基或未取代或取代的芳烷基或芳基; Y是无机,有机或有机金属酸的阴离子,Z是金属阳离子,铵阳离子或鏻阳离子,m,n和o为1至3,p和q为0至4; 并且o,p和q的化学计量比如在式(I)中不会导致任何过量的正电荷或负电荷。 如果需要,取代基可以以这样的方式通过直接键或通过桥-O-或-NR 12 - 彼此连接,形成另外的五元或六元环。 该新颖的记录介质具有高灵敏度和良好的再生特性。
